[0002] In PVD (Physical Vapor Deposition) vacuum coating process, the fixture is a key component for supporting and fixing the product to be coated, and its design is directly related to the efficiency and quality of coating.
[0003] However, traditional PVD vacuum coating fixtures are often simply designed, typically only able to hold a single metal product. This design limits the batch processing capability of the coating process, resulting in low production efficiency. Furthermore, during the coating process, because the product remains stationary, the distribution of the coating material on the product surface may be uneven, especially when the product surface has complex structures or sharp edges, making it difficult to guarantee coating quality. Utility Model Content
[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a PVD vacuum coating tooling fixture, which can effectively solve the technical problems that current fixtures used for PVD vacuum coating can only hold a single product and that the coating quality is difficult to guarantee.
[0005] The technical solution adopted by this utility model to solve its technical problem is:

The workstation plate has a plurality of coating stations arranged in a ring, and each coating station is provided with a rotatable clamping assembly and a rotation linkage assembly for controlling the rotation of the clamping assembly.
[0007] The clamping assembly consists of a pad and an external connecting shaft. The pad is suspended above the corresponding coating station. One end of the external connecting shaft is inserted into the coating station and rotates. The other end of the external connecting shaft is connected to the bottom of the pad and drives the pad to move synchronously.
[0008] The rotation linkage assembly consists of an outer synchronous pulley, an inner synchronous pulley, a station gear, and an inner connecting shaft.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figure 1-3 As shown, this utility model provides a PVD vacuum coating tooling fixture, which is particularly suitable for the coating process of hardware products. It aims to provide an efficient and stable coating tooling fixture to improve coating quality and production efficiency.
[0028] The structure of this tooling fixture includes a workstation plate 1 and a support column 2 fixed to the bottom of the workstation plate 1. The workstation plate 1 serves as the load-bearing platform for the entire tooling fixture. The workstation plate 1 is designed as a flat plate structure with a certain strength and rigidity. The support column 2 is vertically fixed to the bottom of the workstation plate 1 and plays the role of supporting the entire tooling fixture.
[0029] The workstation plate 1 has several coating stations 3 arranged in a ring. Each coating station 3 is designed to accommodate and support the clamping assembly 4 and the rotation linkage assembly 5. To make full use of the space of the workstation plate 1, the edge of the workstation plate 1 has several outwardly extending portions 101. The coating stations 3 are evenly distributed on these extension portions 101 to make full use of the space of the workstation plate 1 and improve coating efficiency. At the same time, each coating station 3 is designed with a precise positioning structure to ensure that the clamping assembly 4 can be accurately installed and operate stably. The clamping assembly 4 and the rotation linkage assembly 5 cooperate with each other. During vacuum coating, the hardware clamped in the clamping assembly 4 can be flexibly rotated, which helps to improve the effect of vacuum coating.
[0030] The clamping assembly 4 consists of a pad 401 and an external connecting shaft 402. The pad 401 is suspended above the corresponding coating station 3 and is used to place the hardware product to be coated. One end of the external connecting shaft 402 is inserted into a hole in the coating station 3 and rotates, while the other end is connected to the bottom of the pad 401, enabling synchronous rotation of the pad 401. To enhance clamping stability, several L-shaped clamping blocks 403 are also installed along the edge of the pad 401. These clamping blocks 403 can be adjusted according to the shape and size of the hardware product to ensure that the product does not shift during the coating process.
[0031] The rotating linkage assembly 5 consists of an outer synchronous pulley 501, an inner synchronous pulley 502, a station gear 503, and an inner connecting shaft 504. The inner connecting shaft 504 is inserted through one end of the coating station 3 near the middle of the station plate 1 and rotates, with the inner synchronous pulley 502 and the station gear 503 fixed on it. The outer synchronous pulley 501 is fixed to the outside of the outer connecting shaft 402 and is linked to the inner synchronous pulley 502 via a belt 505 to achieve synchronous rotation of the clamping assembly 4.
[0032] To reduce rotational friction and improve rotational efficiency, outer bearing component 8 and inner bearing component 9 are respectively installed at the positions where the outer connecting shaft 402 and inner connecting shaft 504 are inserted into the coating station 3. During connection, the outer connecting shaft 402 rotates within the outer bearing component 8, and the inner connecting shaft 504 rotates within the inner bearing component 9.
[0033] A drive motor 6 is installed inside the support column 2. The output end of the drive motor 6 extends upward to the middle of the workstation plate 1 and connects to the main gear assembly 7. The main gear assembly 7 is designed to mesh with all the workstation gears 503. The rotation of the drive motor 6 drives the main gear assembly 7 to rotate, thereby driving all the workstation gears 503 and the inner connecting shaft 504 to rotate synchronously, ultimately achieving synchronous rotation of all the clamping components 4.
[0034] To facilitate the installation and fixing of the tooling fixture, the bottom of the support column 2 is provided with a mounting part 201, and the mounting part 201 is provided with several mounting holes 202, so as to fix the entire tooling fixture in the corresponding position of the coating machine.
[0035] In summary, the PVD vacuum coating fixture provided by this technical solution is equipped with multiple coating stations 3. Each coating station 3 is equipped with a corresponding clamping component 4 and a rotation linkage component 5. During vacuum coating, multiple hardware products can be clamped at one time by the clamping component 4. Moreover, during the coating process, the rotation linkage component 5 continuously rotates the direction and position of the hardware products, improving the stability of the coating process. This not only improves the coating quality but also significantly increases production efficiency.
